Does this thing actually do anything beneficial for the car in terms of power?

I bought the spacer and a AirAid intake and I noticed a difference in power, and throttle response. But I installed both upgrades at the same time so I can't say that one helps more than the other. But I will say that the spacer make an awesome whistle! It took a few miles for it to start but it really sounds like a supercharger! I would buy both, after my install I was able to smoke my tires all the way into second gear.

Power, no. It had a loud whistle and maybe 1 more mile per gallon which was nice.

I purchased this device once before in hopes of adding torque. It doesn't add torque or even increase the mpg on your vehicle. It does however, make a cool noise when you step on the gas. But there is also an annoying whistle sound when you're just driving around. So again, no actual benefits except for "performance sounds". I hope this response provides clarity in your decision.

it reduces electrical noise from the alternator and other electrical devices. If your car interior is noisy independent of the sound system, it will not solve your problem.

I have doubts on this (or similar devices) being that reliable for jump-starting any car with a fully drained battery. The battery in this is about 20% the size/weight of most car batteries, so I don't expect but that much power out of them. Most manuals for these say things like "Don't try cranking the engine over 5 seconds or the battery will be damaged". The reason for that is because it's so small a battery and you're expecting so much power from it that cranking the engine seems like creating a short circuit (which could make the battery explode if kept in that state for over a minute). Although the sales people like to put the "400 amp" labels on these to make it seem big, I doubt you can really get 100 amps for cranking an engine. I've seen a fair number of reviews on units like this saying "It didn't work for me", so feel free to look at those (sometimes the negative reviews give more info than a "Works great" one where that's all they say). Also feel free to see my review of the Peak 1 450 jump starter (and that one has a 18 amp/hour battery, this one is only 5 amp/hour). I'm not trying to make you go after a brand (several brands sell virtually the same thing like Clore, Stanley, Black & Decker and more), but realize it's limitations since it's not a full size car battery.

Yes, from the law of conservation of energy (physics) it's clear that you can't get energy/power for nothing so if you're using this inverter it is drawing power from somewhere (your car battery). However, the car's battery is constantly re-charged when the engine is running so your battery shouldn't run out if you're driving while using the inverter. Also, how fast the battery drains depends on what you have plugged into the inverter. If you're just charging a phone, little power is used as compared to having a hair dryer plugged into it. So, long story short -- don't charge or run high-power devices for long periods of time with this (or any) inverter while your car is turned off because that will quickly drain your battery. If you're driving, you should be fine but your gas mileage will probably go down (conservation of energy again, your car has to get energy from somewhere to be able to recharge your battery -- it gets this energy from gasoline). Hope this helps, sorry for the in-depth info -- I'm an electrical engineer and haven't had a change to 'nerd out' yet today :-)

I do not actually know. I have cleaned my car, around my litter boxes, and another things. It has not run out of power. It seems to be pretty good on that end.

Pretty much nothing. May keep your car a little cooler/warmer. That's all it'll do.

It can do either depending on how it's set up. Lots of different settings for power or fuel economy

this thing is pretty cheaply made, and anything to do with a childs car I would not advise to alter, for safety reasons. Why you ask? Well, if you installed it for whatever your reasons, then you would rely on it so you could stop the car if there was a need to do so, right? Well what happened if it did not work at that moment, when you really needed it to work? Get the point?

It worked fine at first- about 3 months. Then it would buzz when plugged into the lighter. Then my car had some type of electrical issues that cost 2000 to fix that I say was attributed to this power adapter because after the repair my car was fine until I plugged it in again. I trashed mine, but you may have better luck and I may be giving it a bad rating in error, but I truly don't think I'm wrong.

I use it as a benz technician to power our cars while doing software updates. Depending on the model and what components need to be on, I've found it can keep the system voltage anywhere from 13.7 - 12.0v. I doubt any other car requires more power during a software update than an S-class with headlights on (for some reason they're turned on during updates). Some updates also take up to 1.5 hrs, and it's been able to keep up fine.

I would not expect it to increase horsepower. It may by chance or good luck increase power a little but my understanding is that it's a maintenance kind of product for helping to keep the converter clean. Not a solution to a convert that's in bad shape. When a catalytic converter gets plugged you have a significant decrease in power and replacing the converter will return the car to what is normal for the car given its age and condition. But I doubt this stuff would be able to clean out a plugged converter, if the problem is the converter.

It isn't very powerful. It can do a car tire but not an SUV tire. I wish I got a more powerful one. I thought AC power would make it more powerful but it isn't much better than a DC powered unit.

Not very well. It is suppose to speed the airflow to the intake. But it is mostly just for looks. If you attach an electric motor to it, you could use it like a turbo.

Yes it'll power up once you start the car as long as it is plugged in the CIGarette lighter sochet.

It will boost the signal going into the aux jack, acting like a pre-amp. However, it is not designed to power large speakers and can only produce 250mW of power at 32 ohm. So you will get a little boost, but the car amp will still be doing most of the work.

yes it increase MPG and horse power on your car.. I have a very good experience with my Honda accord 99.

It has not effected the performance of the car (I have a V6 as well but its a 3.8) as far as I have noticed and my husband has had his macbook plugged in along with charging his phone while I drove.
